Adaptation to the measuring range appropriate to the sample can be achieved by selecting the most suitable test. Higher concentrations of COD (> 90 000 mg/l) require dilution of the sample with COD-free water.

If the sample has been diluted with water, the result should be multiplied by the dilution factor.
